The resins are diepoxides of the formula <IMAGE> +tr <IMAGE> where A IS AN INTEGER OF AVERAGE VALUE FROM 1 TO 100, EACH R and R1 represents a group <IMAGE> OR -O-(OC)c-R5-(CO)c-O-, each R2 represents -H or a group -(CH2NH)dCOC(R6)=CH2, at least one of the 2a groups R2 representing -(CH2NH)dCOC(R6)=CH2, each R3 denotes a lower alkyl group, or conjointly each pair represents a group of formula -CH2CH2-, -C(R7R8)CO-, <IMAGE> -CH2CH2CH2-, -COCO-, -COCOCO-, or -COC(OH)2CO-, R4 represents a divalent aliphatic, cycloaliphatic, or araliphatic radical, B, C, AND D ARE EACH ZERO OR 1, R5 represents a straight or branched chain aliphatic group or, providing c is 1, it may alternatively represent a group <IMAGE> R6 represents -H or a lower alkyl group, and R7 and R8 each represent -H, -CH3, or -C2H5.
